SB2026021382 - openEuler 24.03 LTS SP1 update for libsoup

Description

This security bulletin contains information about 4 secuirty vulnerabilities.

1) Buffer access with incorrect length value (CVE-ID: CVE-2026-0716)

The vulnerability allows a remote attacker to compromise the affected system.

The vulnerability exists due to a boundary error in process_frame() function when handling WebSocket frames if a non-default configuration is used where the maximum incoming payload size is unset. A remote attacker can send specially crafted data to the application and execute arbitrary code on the system.

2) CRLF injection (CVE-ID: CVE-2026-1467)

The vulnerability allows a remote attacker to inject arbitrary data in server response.

The vulnerability exists due to insufficient validation of attacker-supplied data. A remote attacker can pass specially crafted HTTP request ta to the application containing CR-LF characters and modify application behavior.

3) Information disclosure (CVE-ID: CVE-2026-1539)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to library does not remove data from Proxy-Authorization header when following redirects. A remote attacker can gain access to sensitive information passed via the Proxy-Authorization header. 

4) Stack-based buffer overflow (CVE-ID: CVE-2026-1761)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error within the soup_filter_input_stream_read_until() function when parsing multipart/form-data response. A remote attacker can send specially crafted data to the application, trigger a stack-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
